Could AI ever truly "understand"?

ChatGPT knows how to use the word "tickle" in a sentence but it cannot feel the sensation. Can it then be said to understand the meaning of the word tickle the same way we humans do? In an ongoing debate, AI researchers are teasing apart whether large language models (LLMs) like ChatGPT and Google's PaLM understand language in any humanlike sense. The relationship between embodiment and understanding is one question, along with the nature of intelligence and understanding. Should concepts of meaning, understanding, and intelligence be revisited to create a distinction between how humans and machines understand the world?
